Over the past twenty years, research into the applications of organic semiconductors (OSCs) has intensified rapidly. Though their electron mobility is much lower than that of typical semiconductors, OSCs show promise in low-cost, flexible, lightweight, and environmentally-friendly semiconductor applications. Their hole mobility was found to be comparable to that of amorphous silicon (a-Si), wit...

Understanding exciton behavior in organic semiconductor molecules is crucial for the development of organic semiconductor-based excitonic devices such as organic light-emitting diodes and organic solar cells, and the tightly bound electron-hole pair forming an exciton is normally assumed to be localized on an organic semiconducting molecule. We report the observation of long-range coupling of e...

We present a mechanism that explains the energy-level alignment at organic-organic sOOd semiconductor heterojunctions. Following our work on metal/organic interfaces, we extend the concepts of charge neutrality level sCNLd and induced density of interface states to OO interfaces, and propose that the energy-level alignment is driven by the alignment of the CNLs of the two organic semiconductors...

A facile solution process for the fabrication of organic single crystal semiconductor devices which meets the demand for low-cost and large-area fabrication of high performance electronic devices is demonstrated. In this paper, we develop a bottom-up method which enables direct formation of organic semiconductor single crystals at selected locations with desired orientations. Here oriented grow...

In the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (ZnO) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. Previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...

Nonvolatile organic field-effect transistor (OFET) memory devices based on pentacene/N,N'-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (P13)/pentacene trilayer organic heterostructures have been proposed. The discontinuous n-type P13 embedded in p-type pentacene layers can not only provide electrons in the semiconductor layer that facilitates electron trapping process; it also works as c...
